Physical Replication | Agent Skills Atlas

About this skill

PostgreSQL's physical streaming replication — walsender (primary side, replication/walsender.c) + walreceiver (standby side, replication/walreceiver.c) + slots (replication/slot.c) + synchronous replication (syncrep.c). Covers the streaming protocol variant, hot standby, standby feedback, synchronous commit, WAL sender/receiver state machines, and the physical-slot semantics that differ from logical slots. Loads when the user asks about streaming replication, hot standby, pgbasebackup, synchronouscommit levels, walsender/walreceiver state, primaryconninfo, physical replication slots, standby feedback (hotstandbyfeedback), or pgwalreplay recovery-progress functions. Skip when the ask is about logical replication (replication/logical/) — sibling but very different code path.

Original description

PostgreSQL's physical streaming replication — walsender (primary side, `replication/walsender.c`) + walreceiver (standby side, `replication/walreceiver.c`) + slots (`replication/slot.c`) + synchronous replication (`syncrep.c`). Covers the streaming protocol variant, hot standby, standby feedback, synchronous commit, WAL sender/receiver state machines, and the physical-slot semantics that differ from logical slots. Loads when the user asks about streaming replication, hot standby, `pg_basebackup`, synchronous_commit levels, walsender/walreceiver state, primary_conninfo, physical replication slots, standby feedback (`hot_standby_feedback`), or `pg_wal_replay_*` recovery-progress functions. Skip when the ask is about logical replication (`replication/logical/`) — sibling but very different code path.
